    A Special Note about Email accounts!
    DO NOT SIGN UP USING hotmail, outlook, gmx, sbcglobal, att, bellsouth or email.com. They delete our forum signup emails.

    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

I have a 1980 gs850gt that has 40,000 miles. I get a reading of only 85 lbs. in each cylinder 90 if I add an oz. of oil. Bike runs great , I think that with the CV carbs. the slides are down when its at rest, so even though I'm holding the throttle open and the choke is off as I'm cranking, the slides are down restricting intake hence the low readings.
Do I figure this right, should I be worried?
 
Worried? No. But you can get higher readings. I get readings of 125+ on mine with CV carbs. Doesn't sound like rings with only +5 PSI. Was that hot?

40k miles, huh? When was the last time you did a valve adjustment?
